For static-only DHCP, i.e. with no <range> but at least one <host>
element within <dhcp> element, we have to add "--dhcp-range IP,static"
option to dnsmasq to actually enable the service. Without this option,
dnsmasq will not respond to DHCP requests.
QMP in QEMU 0.13 has been fixed to enforce type correctness,
this means that boolean types must be true or false, not
integers.

Before this commit SessionIsActive was not used because ESX(i)
doesn't implement it. vCenter supports SessionIsActive, so use
it here, but keep the fall back mechanism for ESX(i) and GSX.
QueryVirtualDiskUuid is only available on an ESX(i) server. vCenter
returns an NotImplemented fault and a GSX server is missing the
VirtualDiskManager completely. Therefore only use QueryVirtualDiskUuid
with an ESX(i) server and fall back to path as storage volume key for
vCenter and GSX server.
VirtualDisks are .vmdk file based. Other files in a datastore
like .iso or .flp files don't have a UUID attached, fall back
to the path as key for them.
This patch adds support for ethernet interface type to OpenVZ domains
as stated in this previous message: http://www.redhat.com/archives/libvir-
list/2010-July/msg00658.html
Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:
"[datastore] directory/file"
was split into this before:
datastoreName = "datastore"
directoryName = "directory"
fileName = "file"
Now it's split into this:
datastoreName = "datastore"
directoryName = "directory"
directoryAndFileName = "directory/file"
This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.
Update the tests accordingly.
snprintf is currently implicitly picked up by getaddrinfo, but we
might as well make it explicit so that mingw doesn't break if
getaddrinfo changes to drop the dependency.
func doesn't matter for gcc compilation, but may help other compilers
cope with our use of __func__.
* bootstrap.conf (gnulib_modules): Add snprintf and func.
Virsh shouldn't check for driver support but rather let the backend handled this.
After removing the check, I can successfully attach file-based images to a qemu
VM with attach-disk.
% virsh attach-disk vm2 /images/test02.img vdc --driver qemu --type disk --subdriver raw
Disk attached successfully
This command generates the following XML:
<disk type='block' device='disk'>
<driver name='qemu' type='raw'/>
<source dev='/images/test02.img'/>
<target dev='vdc' bus='virtio'/>
<alias name='virtio-disk2'/>

For privileged UML connections (uml:///system), we shouldn't use root's
home dir, but rather somewhere in /var/run/libvirt/uml-guest.

uml_dir overrides user-mode-linux's default of ~/.uml. This is needed
for a couple of different reasons:
libvirt expects this to default to virGetUserDirectory(geteuid()) +
'/.uml'. However, user-mode-linux actually uses the HOME environment
variable to determine where to look for the uml sockets, but if running
libvirtd under sudo (which I routinely do during development), $HOME is
pointing at my user's homedir, while my euid is 0, so libvirt looks in
/root.
Also (and this was my actual motivation for this patch), if HOME isn't
set at all, user-mode-linux utterly fails. Looking at the code, it seems
it's meant to emit a warning, but alas, it doesn't for some reason.
If running libvirtd from upstart, HOME is not set, so any system using
upstart will need this change.

Xen4.0 includes a new blktap2 implementation, which is specified
with 'tap2' prefix. AFAICT it's configuration syntax is identical
to blktap, with exception of 'tap2' vs 'tap' prefix. This patch
takes the simple approach of accepting and generating sexp
containing 'tap2' prefix.
When creating a new domain from XML, the check for an existing
domain name should compare the return of the function to a valid
LPAR ID (!= -1) and not to error (== -1).
The check was altered in 8c48743b97
and got too strict, I've no clue how that snuck in. This check
makes every try to open a connection using the ESX driver fail
with an invalid argument error.
Revert the change to the check and add a comment to prevent future
mistakes with this check.
Since libvirt-guests init script and its configuration do not require
libvirtd to be running/installed, it was a bad idea to put them into
daemon directory. libvirt.spec even includes these files in
libvirt-client subpackage, which may result in build failure for
client-only builds when the whole daemon directory is just skipped.
UML supports hot plugging and unplugging of various devices. This patch
exposes this functionality for disks.

Other drivers will need this same functionality, so move it to up to
conf/domain_conf.c and give it a more general name.

When finding a sparse NUMA topology, libnuma will return ENOENT
the first time it is invoked. On subsequent invocations it
will return success, but with an all-1's CPU mask. Check for
this, to avoid polluting the capabilities XML with 4096 bogus
CPUs
* src/nodeinfo.c: Check for all-1s CPU mask
Enabling debug doesn't show the capabilities XML for a connection.
Add an extra debug statement for the return value

When failing to serialize the normal RPC reply, try harder to
send a error message back to the client, instead of immediately
closing the connection.
* daemon/dispatch.c: Improve error messages when RPC reply
can not be sent
When libvirtd fails to serialize a message to XDR the client
connection is terminated immediately. To enable this to be
diagnosed, log the message which caused the problem on the
server
* daemon/dispatch.c: Log XDR serialization failures
Like the comment suggested, we just open the file and pass the file
descriptor to uml. The input "stream" is set to "null", since I couldn't
find any useful way to actually use a file for input for a chardev and
this also mimics what e.g. QEmu does internally.

Instead of using one big traversal spec for lookup use a set of
more fine grained traversal specs that are selected based on the
actual needs of the lookup.
This gives up to 20% speedup for certain operations like domain
listing due to less HTTP(S) traffic.
RHEL-5 Xen doesn't support the old style vnc configuration. In sexpr, we
can't really check it with rhel5-api turned on. However, for XM
configuration files it's sufficient to use cfg version 1 instead of 2.
The most common cause of errors with rhel5-api turn on was missing
"(type ioemu)" in sexpr or its equivalent in XM configuration file. This
happens because the presence of that part in sexpr (or cfg) depends on
xen version the host is running. Let's avoid it by explicitly specifying
interface model which ensures "type ioemu" will always be emitted.
This patch adds
<model type='e1000'/>
withing the interface element in all affected xml files. And
(model 'e1000')
to all corresponding sexpr files with similar fix to cfg files. Such
configuration works regardless on Xen version.
